Push vs Pull for H100i

shootersam · 7 Jul 2014 at 15:26

First time ever using a radiator, and the whole push vs pull is confusing me.

I want the least amount of dust build up possible, so was thinking about having my fans on the bottom of my radiator taking the air from the case and then through the radiator.

What would be the best set up for this radiator in the 250D case?

Thanks.

if air goes
Air->Rad->fans->out
it's easy to clean the rad
If it goes:
Air->Fan->Rad->air
You need to take the fans off to clean the rad

Dust filters help a lot but restrict airflow too

As Giraffe said - Push through a rad makes it awkward to clean.
I swapped back to pull just yesterday for this very reason. I strip down and dust out my entire rig out *at least* once a month and the amount of crap between fan and radiator from just since I last cleaned it (approximately 3 weeks) was insane...!!!
I'm not exactly a cleaning fanatic, but I've only seen that level of dust behind a wardrobe that hadn't moved in 5 years!!

I assume you're using the stock H100i fans?
If not, make sure the ones you are using have high static profile and don't overlap the rad (as many 140mm ones do) or draw in from the side (like Enermaxes) as you lose performance.

So for pull, should my fans be set to pull air from the case through the rad?

Inside case->rad->Fan-> outside case.

Or you can do Outside case->rad->fan->inside and pull cool air in through the rad, but I'm not familiar with your case

So for this, the fan would be pulling air from the case, through the rad, and exhausting out of the case?

Sorry for being dim
